The General Instruments AY-3-8470 256 command infrared remote control
transmitter and AY-3-8475 remote control reciever can be connected to
a keyboard array, and generate 8 bit codes which are transmitted 
through a fairly simple 3 transistor circuit. The reciver can be made
is basically a connected to a infrared LED and amplifier. Depending on
how good your amplifier is it is also rather simple. (GI uses a TDA4180
dual opamp amplifier, but a LM386 should work fine.) Any additional
info is available through there distibutor.
